Kubernetes in Production Best Practices

By: Aly Saleh, Murat Karslioglu

Overview of this book

Although out-of-the-box solutions can help you to get a cluster up and running quickly, running a Kubernetes cluster that is optimized for production workloads is a challenge, especially for users with basic or intermediate knowledge. With detailed coverage of cloud industry standards and best practices for achieving scalability, availability, operational excellence, and cost optimization, this Kubernetes book is a blueprint for managing applications and services in production. You'll discover the most common way to deploy and operate Kubernetes clusters, which is to use a public cloud-managed service from AWS, Azure, or Google Cloud Platform (GCP). This book explores Amazon Elastic Kubernetes Service (Amazon EKS), the AWS-managed version of Kubernetes, for working through practical exercises. As you get to grips with implementation details specific to AWS and EKS, you'll understand the design concepts, implementation best practices, and configuration applicable to other cloud-managed services. Throughout the book, you’ll also discover standard and cloud-agnostic tools, such as Terraform and Ansible, for provisioning and configuring infrastructure. By the end of this book, you’ll be able to leverage Kubernetes to operate and manage your production environments confidently.

Chapter 7: Managing Storage and Stateful Applications

In the previous chapters, we learned how to provision and prepare our Kubernetes clusters for production workloads. It is part of the critical production readiness requirement to configure and fine-tune day zero tasks, including networking, security, monitoring, logging, observability, and scaling, before we bring our applications and data to Kubernetes. Kubernetes was originally designed for mainly stateless applications in order to keep containers portable. Therefore, data management and running stateful applications are still among the top challenges in the cloud native space. There are a number of ways and a variety of solutions to address storage needs. New solutions emerge in the Kubernetes and cloud-native ecosystem every day; therefore, we will start with popular in-production solutions and also learn the approach and criteria to look for when evaluating future solutions.

In this chapter, we will learn the technical challenges...
